The irreplaceable mother of rolled products—CNC roll grinder
The roller is known as the mother of rolled materials, and every piece of rolled material is rolled by a roller. Therefore, the quality of the rolls is directly related to the surface quality of the rolled material and restricts the rolling mill operation rate and rolling mill output.
The roll is a tool that causes plastic deformation of the metal (rolled material). It is an important consumable component that determines the efficiency of the rolling mill and the quality of the rolled material.
Roll types can be divided into cast rolls and forged rolls according to the forming method; they are divided into integral rolls, metallurgical composite rolls and combined rolls according to the process method. Integral rolls are divided into two types: integral casting and integral forging rollers.
There are three main types of metallurgical composite casting rolls: semi-flushing composite casting, overflow (full flushing method) composite casting, and centrifugal composite casting. In addition, there are also special ones such as continuous casting coating, spray deposition method, hot isostatic pressing, and electroslag welding. Types of composite rolls manufactured by composite methods. The combined roller is mainly a nested combined roller.
Rolls are mainly divided into three categories based on manufacturing materials: cast steel series rolls, cast iron series rolls and cast series rolls. Among them, cast iron-based materials with a carbon content of less than 2.2% are called cast steel series; cast iron-based materials with a carbon content greater than 2.2% are called cast iron series; and forged iron-based materials are called forged series.
The CNC roll grinder is an important supporting equipment for the steel plate rolling production line. It consists of several core modules such as electrical control system, drive system, grinding system, measurement system, and load-bearing system.
